NOTCHING MECHANISM FOR CAN-BODY BLANKS.

Specification of Letters Patent.

Patented Mar. 19, 1912.

Application filed January 28, 1910. Serial No. 540,558.

To all whom it may concern:

machinery, and more particularly to a' mechanism for treating the edgesof a blank preparatory to forming the same into a can body Morespecifically stated, the invention relates to a mechanism for removing apart or'parts of an edge or edges of a blank, preliminary to forming thesame into a can body of a certain type.

One of the objects of the invention is to produce a device of the kinddescribed, generally known as a notcher, which is particularly compactin its structural arrangement, and simple in the disposition and mode ofoperation of its parts.

Another object is to provide, in a device of the kind described, a dieand a cooperating notcher having inter-engaging portions, whereby theoperating parts will reciprocally guide one another.

Still another object is to mount the movable member of a die-and-notchermechanism upon a shaft, making possible an efficient and economicaldrive with a minimum of operating parts, and subserving compactness.

A further and more specific object is to provide the parts of adie-and-notcher with portions embracing the operating shaft, one of theoperating parts being rotatable with the shaft and with respect to theother parts.

A further object is to provide the die member of such a mechanism withspaced portions engaging a driving shaft, and the notcher member with aportion embracing the shaft between said spaced portions of the diemember, one of said members, preferably the notcher member, being fastonthe shaft.

I also aim to provide a shaft-driven and supported mechanism of the kindreferred to, which is driven by practically direct and very slmpleconnections with the main shaft ofa can machine.

Furthermore, (and the attainment of this object is rendered possible bythe disposition of parts indicated above) I aim to provide a notcher inwhich the operating parts are readily and simultaneously adjustable.

Other objects and aims of the invention, more or less broad than thoseabove-stated, together with the advantages inherent, will be in partobvious and in part specifically adverted to in the course of thefollowing description of the elements, combinations and arrangement ofparts constituting the invention, and the scope of the applicationthereof will be defined in the appended claims.

In the accompanying drawings, which are to be taken as a part of thisinvention, and in which I have shown a merely preferred form ofembodiment of the invention as applied to a can making machine: Figure 1is a vertical sectional view, partly elevation, of a can machine inwhich this invention is applied; Fig. 2 is a sectional plan view of thesubject matter of Fig. 1; Fig. 3 is a front elevation, partly insection, of a notcher device embodying the invention, showing theimmediate driving connections; Fig. 4 is a detail view of the notcherproper; Fig. 5 is a sectional view, partly in elevation, on the line 55of Fig. 3; Fig. 6 is a section on the line 66 of Fig. 3; and Fig. 7 is aschematic plan view, partly in section, illustrating the relation ofdevices embodying this invention to the bed of a can body machine, alongwhich blanks are fed into operative juxtaposition with said device.

Referring to the. numerals on the drawings, 1 indicates the frame of amachine embodying various mechanisms necessary for different treatmentsof a blank, and for the orderly progression of the latter to each ofsaid mechanisms. In a preferred machine I provide a main drive shaft 2,which may me actuated by means of a pulley 3 exteriorly of the machine.

4 indicates a bed arranged centrally of the machine, and 5 areciprocating blank feed, which is adapted to move a blankintermittently along said bed, the reciprocating feed being preferablyactuated by suitable connections with the drive shaft 2. In the movementof the blank along the bed it is a closure 17 for presented in turn tonotching mechanisms 6 disposed at opposite sides of the bed 4, and whichwill be hereinafter more particularly described; thence to edging orhook forming devices 7, arranged on opposite sides of the bed;and-thence to a horn 8 about which it is bent by suitable mechanism intoa can body. The edging means, the horn, and other parts of the machineare driven by suitable connections with the drive shaft, but detaileddescription thereof, and of their relation to the machine, is deemedunnecessary for the purposes of this specification, and because the samemay be found in a copending application Serial No. 540,569 filed ofevendate.

Referring now more particularly to the notching mechanism, it should beunderstood that the purpose of this device is to remove portions of ablank edge, in the form of a notch or incision, as is. necessary in themanufacture of certain types of cans. To this end a blank is fed alongthe bed 4 edge- W158 intermittently, so that one of its phases ofmovement presents it in operative relation to the notching mechanisms 6,which are positioned in alinement at opposite sides of the bed. Here thenotching mechanism,

.by properly timed actuations, operates to cut a notch or notches in thepresented edge portion of the blank. It is to be understood that while Ihave shown the notchi ng mechanism at opposite sides of a machineoperating on opposite edges of the blank, they are adapted for usesingly. And inasmuch as the mechanisms shown are substantially identicalin construction, except for such differences as are due to their opposedrelation in the machine, I shall describe but one of them.

Each of the notcher mechanisms 'comprises a box-like casing 9, which isprovided at opposite ends With bearings 11 and 12 for a shaft 14. At oneend the said casing is provided with a tubular extension 15 beyond thebearing 11, and the said shaft 14 projects into said tubular extension.Within said extension the shaft is provided with a pinion 16, and beyondsaid pinion there is the tubular extension. Preferably cast integralwith the casing as thus far described is a sleeve 18, disposedtransversely of the shaft bearings, and opening into the tubularextension. Within said sleeve is adapted to reciprocate a rack rod 19,which engages the pinion 16, and in its reciprocation rocks the shaft14.

The shaft 14 is provided with a longitudinal key-way 21 and within saidkey-way is adapted to engage a correspondingly formed key 22 on anotcher member 24, which comprises an annular support or eollar25adapted to be slid onto the shaft and having an integral, preferablysegmental, cutting member 26, which may be of any preferred crossin Fig.6, and abuts at its rear end against the lower part of the casing,'towhich it 1s.

secured as by means of a bolt 31.

From the description thus far given it is evident that the die portion29 is fixed in the casing, While the notcher proper oscillates towardand from it, being retained in its working position by the collars 27and 28. The bolt fastening 31 for the die preferably passes through aslot 32 in the casing, and obviously upon loosening the bolt the die maybe slid along the shaft, carrying the notcher with it, so thatadjustments of the die and notcher longitudinally of the shaft may bemade simultaneously. I have shown each shaft provided with two of, thedies and cooperating notchers, and only one set of them, indicated bythe numeral 34 in Fig. 3, is adjustable in the slot 32,.the fastening ofthe other being through ordinary bolt holes.

The die member 29 is provided with an aperture 35 extending therethroughfrom the face down, and a removable die plate 36- is carried on theface, being provided with a notch shaped conformably with thecrosssection of the notcher part 26. It will be seen that as the shaft14 is rocked, the notcher 26, moving with the shaft, will approach thedie 29, and cut out a correspondingly shaped piece from the edge of theblank which overlies the die. The cut out piece is forced through thenotch in the removable die plate and thence falls through the aperturein the die.

It will be observed that the collar 25 is of slightly larger diameterthan the guiding collars 27, 28, and that die-plate 36 is cut out anddisposed to snugly fit collar 25, so that engagement of notcher 26 withits notch in the die-plate may be at all times assured.

The rack rod 19 which drives the shaft 14, as already described, isreciprocated as by means of a link 37 connected to an eccentric strap 38which is driven from an eccentric 39 on a shaft 41 that extendstransversely of the machine and which is driven by suitable connectionswith the main drive shaft in an obvious manner.

In Fig. 1, I have shown the bed comprising two parts in longitudinalparallelism, but movable relatively to each other, as by means ofsupporting pinions 42, movable on the frame of'the machine. In thismanner I am enabled to adapt the bed for the accommodation ofdifierentsized blanks. In View section, or as shown in the drawings:Closely embraclng the member 25 are spaced of this adaptability thenotchers should be adjustable toward and from each other on oppositesides of the bed, and to this end they may be carried on the sides ofthe bed, as shown at 4 t in Fig. 1. This attachment is preferablythrough the intermediary of a bracket 4.5, upon which the casing is heldin adjustab e relation by means of a bolt and slot connection indicatedat to in Fig. (3. If the bed members, with the attached notching devicebe moved, it will, of course, be necessary to move the eccentric 3!)along the shaft.

As many changes could be made in the above construction and manyapparently widely different embodiments of my invention could be madewithout departing from the scope thereof, it is intended that all mattercontained in the above description or shown in the accompanying drawingsshall be interpreted as illustrative merely and not in a limiting sense.It is also to be under stood that the language used in the followingclaims is intended to cover all of the generic and specific features ofthe invention herein described and all statements of the scope of theinvention which, as a matter of language, might be said to falltherebetween.
